Abstract
The utility model relates to a worm and gear speed reducer for a forklift accessory, and aims to provide a worm and gear speed reducer which is simple in structure, high in manufacturing process and low in cost, saves materials and is used for a forklift accessory. The worm and gear speed reducer which is connected integrally by a screw plug, a stuffy cover, a gasket, a conical roller bearing, a shell, a gear shaft, a flat key, a check ring for a shaft, an oil seal, a worm, a conical roller bearing, a through cover, an oil motor, a two-way hydraulic lock, a single-way hydraulic lock, a deep groove ball bearing, a worm gear, a deep groove ball bearing, a rear cover and a vent plug by a bolt and the flat key, wherein the two-way hydraulic lock can realize two-way hydraulic self latching. The worm and gear speed reducer is characterized in that the oil motor is rotated by the driving of a hydraulic system of a forklift, is connected with the worm by a spline and transfers torque to drive the worm to rotate; the worm is matched with the worm gear; the worm gear is connected and matched with a gear shaft by the flat key; and the worm is driven to drive the worm gear to rotate, so that the gear shaft is driven to rotate 360 degrees along forward and backward directions.
Description
Technical field
The utility model relates to industrial vehicle fork truck Special accessory, relates in particular to a kind of lift truck attachment worm type of reduction gearing.
Background technology
High speed development along with Chinese national economy, the demand of lift truck attachment and day sharp increase, scope of work is more and more wider, and the user is also more and more higher to the operating needs of lift truck attachment, the function of suitable, contrary 360 ° of rotations of both direction that the part lift truck attachment has can improve operating efficiency greatly.The rotation class accessory of existing domestic each large fork truck main engine plants coupling mainly also relies on external product, and weak point has: procurement price is very high, has increased the manufacturing cost of fork truck; Procurement cycle is long, can not satisfy user's demand; Consumable accessory buying difficulty and expensive, maintenance difficult.
The utility model content
The purpose of this utility model provides a kind of not only its service property (quality) performance and external product is equal to, and designs simplification, saving material, manufacture craft are good, the lift truck attachment worm type of reduction gearing that Costco Wholesale is low.
In order to address the above problem, the utility model is achieved through the following technical solutions:
Lift truck attachment worm type of reduction gearing of the present utility model, by plug screw, stifle, pad, tapered roller bearing, housing, gear wheel shaft, flat key, shaft block ring, oil sealing, worm screw, tapered roller bearing, transparent cover, oil motor, bidirectional hydraulic lock, one-way hydraulic lock, deep groove ball bearing, worm gear, deep groove ball bearing, bonnet and porous plug pass through bolt, flat key connects in aggregates, described bidirectional hydraulic lock can be realized the bidirectional hydraulic self-locking, described oil motor rotates under forklift hydraulic system drives, described oil motor is connected with worm screw and transmitting torque by spline, driving worm screw rotates, worm and wheel cooperates, worm gear is connected cooperation with gear wheel shaft by flat key, under worm drive, worm screw drives the worm gear rotation and then the driven gear axle can be along suitable, contrary 360 ° of rotations of both direction.
Further, described gear wheel shaft tooth Shape Design is short tooth, has improved the load-carrying capacity of the gear teeth.
Further, described worm gear and worm screw are adopted the profile of tooth of single start worm, involute, both can raise the efficiency, reduce egress of heat, can realize auto-lock function again.
Further, described housing, bonnet, stifle, transparent cover all adopt the QT450 mono-block cast, the little and good looking appearance of volume.
Further, the core wheel of described worm gear adopts forging, wheel rim to adopt foundry goods, centrifugal castingin on core wheel, large increase the load-carrying capacity of worm gear, the safety when having guaranteed work.
Further, described worm screw, whole nitrogenize is carried out in the modifier treatment of worm screw elder generation again, the centering mode of rectangular spline is path centering, overall enhanced the load-carrying capacity of worm screw.
Compared with prior art, the beneficial effects of the utility model are: the utility model makes suitable, the contrary 360 ° of rotations of both direction of reducer gear axle energy by hydraulic-driven, drive suitable, the contrary 360 ° of rotations of both direction of accessory energy, thereby the fork that makes things convenient for goods is got and is stacked, the two-way pressurize self-locking of retarder bidirectional hydraulic lock energy, worm and gear self auto-lock function have not only improved the operating efficiency of fork truck but also have guaranteed the safety when working simultaneously.
Its advantage is: 1, hydraulic efficiency pressure system aspect: retarder has adopted bidirectional hydraulic lock, to realize bidirectional hydraulic self-locking, the safety when guaranteeing work.2, framing member aspect: housing, bonnet, transparent cover, stifle adopt QT450 inblock cast structure, have both guaranteed intensity, make again good looking appearance; Worm gear and worm screw are adopted the profile of tooth of involute, both can raise the efficiency, reduce egress of heat, can realize auto-lock function again.3, Costco Wholesale is lower than external product 35-45%, and its extensive market, technical economic benefit are very considerable.
